The live action How to Train Your Dragon cast brings the beloved Viking world of Berk into a realistic setting while keeping the heart of the original animated story. Released in 2025, the movie features Mason Thames as Hiccup, Nico Parker as Astrid, and Gerard Butler returning as Stoick. The cast combines young performers with experienced actors to recreate one of DreamWorks’ most recognizable fantasy adventures.
Who Is in the Live Action How to Train Your Dragon Cast?
The live-action adaptation features a largely new group of actors compared with the original animated trilogy. Mason Thames takes the central role of Hiccup, while Nico Parker plays Astrid Hofferson.
Gerard Butler returns to the franchise as Stoick the Vast, making him the most notable connection between the animated and live-action versions. He originally provided Stoick’s voice in the animated films and now portrays the character physically.
Other major cast members include Nick Frost, Julian Dennison, Gabriel Howell, Bronwyn James, and Harry Trevaldwyn.
The casting gives the remake a mixture of recognizable performers and younger actors who can portray the teenage Viking characters.
Mason Thames as Hiccup
Mason Thames plays Hiccup Horrendous Haddock III, the central character of the movie. Hiccup is the son of Stoick and a young Viking who does not fit the traditional image of a warrior.
Instead of being naturally powerful or aggressive, Hiccup relies on intelligence, creativity, and problem-solving. His life changes when he encounters Toothless, a Night Fury that he initially captures but ultimately chooses to help.
Thames was previously known for roles including The Black Phone. His performance as Hiccup requires him to balance humor, vulnerability, courage, and emotional growth.
The character’s journey remains one of the most important elements of the franchise.
Nico Parker as Astrid Hofferson
Nico Parker portrays Astrid Hofferson, one of Berk’s strongest young Viking warriors.
Astrid is confident, determined, competitive, and highly capable. At first, she has little reason to believe Hiccup could become a successful dragon trainer. Her relationship with him gradually changes as she discovers that his unusual approach to dragons may actually be the key to understanding them.
Parker brings experience from projects including The Last of Us and Dumbo. Her casting gives the live-action Astrid a fresh interpretation while maintaining the character’s importance to Hiccup’s story.
Astrid is more than a supporting character because her reactions help the audience understand how dramatically Hiccup’s ideas challenge Viking traditions.
Gerard Butler as Stoick the Vast
Gerard Butler plays Stoick the Vast, Hiccup’s father and the chief of Berk.
Butler’s return is one of the most interesting aspects of the live action How to Train Your Dragon cast. Unlike nearly every other major human character, Stoick is played by the same performer associated with the animated franchise.
Stoick is a powerful Viking leader who believes dragons represent a serious threat to his people. His relationship with Hiccup is complicated because he loves his son but struggles to understand his personality and choices.
Butler’s experience with the character allows the live-action version of Stoick to retain a familiar emotional quality while giving audiences a physical interpretation of the Viking chief.
Nick Frost as Gobber
Nick Frost plays Gobber the Belch, Berk’s blacksmith and one of Stoick’s closest advisers.
Gobber has an important role in the village and frequently provides practical advice to Stoick and Hiccup. His experience as a craftsman also makes him an important figure in Hiccup’s development.
Frost is particularly well known for comedic performances, but Gobber requires a combination of humor, loyalty, toughness, and warmth.
The live-action interpretation gives Frost an opportunity to bring his recognizable comedic timing to a character longtime fans already know.
The Supporting Cast of Berk
The live action How to Train Your Dragon cast also includes several actors portraying Hiccup’s fellow young Vikings.
Julian Dennison plays Fishlegs, a character known for his knowledge of dragons and generally gentle personality. Gabriel Howell portrays Snotlout, a confident and competitive young Viking.
Bronwyn James plays Ruffnut, while Harry Trevaldwyn takes on the role of Tuffnut. Ruth Codd also appears as Phlegma.
Together, these characters form the younger Viking group around Hiccup and help show the different attitudes that exist within Berk.
Their presence also adds humor and energy to the training sequences and village scenes.
Live Action Cast vs. Original Animated Cast
One of the easiest ways to understand the new adaptation is to compare its performers with the actors from the original animated movie.
| Character | Live-Action Actor | Original Animated Voice |
|---|---|---|
| Hiccup | Mason Thames | Jay Baruchel |
| Astrid | Nico Parker | America Ferrera |
| Stoick | Gerard Butler | Gerard Butler |
| Gobber | Nick Frost | Craig Ferguson |
| Fishlegs | Julian Dennison | Christopher Mintz-Plasse |
| Snotlout | Gabriel Howell | Jonah Hill |
| Ruffnut | Bronwyn James | Kristen Wiig |
| Tuffnut | Harry Trevaldwyn | T.J. Miller / Justin Rupple |
The comparison shows that Gerard Butler is the major returning performer. Most of the original voices were replaced because the live-action production required actors who could physically portray the teenage characters.
How the Cast Changes the Original Story
The live-action movie follows the basic story established by the animated film, but seeing the characters as real people changes the tone.
Hiccup’s relationship with Toothless becomes particularly important because the audience sees a physical environment rather than an entirely animated one. The Vikings, village, costumes, dragons, and landscapes are presented with a more realistic visual approach.
The performances also help make the emotional conflicts feel grounded. Hiccup’s struggle to gain his father’s approval, Astrid’s changing opinion of him, and Stoick’s fear of dragons all become central dramatic elements.
The casting therefore has to preserve the personalities fans remember while making those personalities believable in a live-action setting.
Why Gerard Butler’s Return Matters
Gerard Butler’s return as Stoick is especially meaningful for longtime fans.
He originally voiced Stoick in the animated trilogy, meaning he already understood the character’s personality, relationship with Hiccup, and emotional importance to the story.
Having the same actor return creates continuity between the two versions. At the same time, the performance is different because Butler is now physically appearing as Stoick rather than providing only his voice.
This makes Butler one of the most recognizable links between the original and remake.
What Makes the New Cast Stand Out?
The strength of the new cast comes from the balance between established performers and younger actors.
Mason Thames and Nico Parker carry much of the teenage storyline, while Gerard Butler and Nick Frost provide experience and familiarity. The supporting actors help create the larger community of Berk.
The casting also allows the film to introduce the franchise to viewers who may never have watched the animated movies.
For existing fans, meanwhile, the performances provide a new interpretation of familiar characters without completely abandoning the personalities that made the original popular.
